The average cost of everyday household goods and services went up by 0.6% in the year to August.
The UK inflation rate, as measured by the Consumer Prices Index (CPI), was unchanged from July.
Rising food prices and air fares pushed prices higher, the Office for National Statistics said, partly offset by cheaper prices for hotel rooms.
ONS statistician Mike Prestwood told the BBC that raw material costs had ‘risen for the second month running, partly due to the falling value of the pound’.
He added there was ‘little sign of this feeding through to consumer prices yet’.
But house price inflation across the UK fell to 8.3% in the year to July, down from 9.7% in June, according to official statistics.
They show that he average house price across the UK in July rose to £217,000.
The report says: “The East of England is the region which showed the highest annual growth, with prices increasing by 13.2% in the year to July 2016.
“Growth in London remains high at 12.3%, followed by the South East with an 11.9% annual growth.
“The lowest annual growth was in the Yorkshire and The Humber, where prices increased by 4.7% over the year.”
